  ## [0.1.0] — 2026-05-26 First release. Lean MVP of a native Android client for MongoDB, talking directly to any deployment reachable over `mongodb://` or `mongodb+srv://` (Atlas, self-hosted, replica sets, sharded). Side-load only for this release. ### Added — Connection management - Save multiple named connections. URIs including embedded passwords are encrypted at rest with AES/GCM via Android Keystore (key alias `mongo_client_master_v1`, never leaves secure storage). - Connection editor with show/hide password toggle (in-place character masking, cursor offsets preserved). - **Test** button that probes the URI without saving. - Light structural URI parser for live editor validation (no network calls on the UI thread). ### Added — Browsing - Database list with size on disk and empty-state indicators. - Toggle to show/hide `admin` / `local` / `config` system databases; default configurable in Settings. - Collection list with type chips (view, time-series) and estimated document counts. - Per-collection **Documents** / **Indexes** tab switcher. - Compass-style type-to-confirm dialogs for dropping databases or collections. ### Added — Documents (find + CRUD) - Paginated `find` with skip / limit (25/page default); prev/next pager. - Filter, projection, and sort fields as raw JSON with per-field inline parse error reporting. - Status header showing `Showing X–Y of N`; fast metadata count for unfiltered queries, exact `countDocuments(filter)` for filtered ones. - Document detail view with formatted, syntax-highlighted JSON; selectable for copy-paste. - JSON editor for insert and edit with live parse validation, **Format** button, and auto-generated `ObjectId` pre-filled in the insert template (editable). - Single-click confirm dialog for document deletion. - BSON ↔ JSON round-trip via MongoDB Extended JSON v2 (RELAXED mode); `ObjectId`, `Date`, `Long`, etc. render readably and survive edits. ### Added — Indexes - Read-only index list per collection. - Per-index card shows name, keys with `↑`/`↓` direction (or `2dsphere` / `text` / `hashed` verbatim), chips for `unique` / `sparse` / `TTL` / `partial`. - Tap-to-expand reveals the raw JSON definition. ### Added — Adaptive UI - `WindowSizeClass`-driven layouts: three-pane (databases · collections · content) on Expanded; stacked nav with back-handler on Medium and Compact. - Hand-tuned blue-grey Material 3 ColorScheme for light and dark modes. - Settings screen — theme picker (System / Light / Dark) and default show-system-databases toggle; persisted via DataStore. - Sextant-themed adaptive launcher icon (white sextant silhouette on blue-grey). - Connection-lost banner with in-place **Reconnect** so a transient drop doesn't force a trip back to the connection list. - JSON syntax highlighting (keys / strings / numbers / `true`/`false`/`null`) in document cards, detail views, editor, and index raw views; palette adapts to both modes. ### Added — Reliability - Centralised Mongo error mapping: cryptic driver exceptions render as "Authentication failed", "Connection lost", duplicate-key, not-authorised, etc. - SLF4J `slf4j-simple` binding so connection-thread errors surface in logcat instead of vanishing into the NoOp logger. - 24 unit tests across connection-string parsing, JSON formatting/parsing, JSON syntax tokenisation, and index-definition parsing. ### Added — Build / release infrastructure - Signed release APK + AAB build with R8 + resource shrinking enabled. - Tuned ProGuard rules for MongoDB driver internals, Netty, Conscrypt, Hilt-generated code, Room, and the in-app SASL stubs. - `versionCode` and `versionName` sourced from `version.properties` — single source of truth, bumped manually per release. - 512×512 Play Store listing icon at `play_store/icon-512.png`, generated from a tracked SVG. - README with build / run instructions, credential-storage explainer, known limitations, and signed-release procedure. ### Internal — Android compatibility for the MongoDB driver The official Kotlin coroutine driver doesn't ship Android-ready. Five distinct compatibility layers are required and shipped with this release: 1. Custom `com.mongodb.spi.dns.DnsClient` implementation backed by `dnsjava` (Android omits the `javax.naming.*` JNDI packages the driver uses for SRV/TXT resolution). 2. Netty transport (`io.netty:netty-handler`) substituted for the driver's vendored TlsChannel, which has a NIO buffer-state bug on Android that stalls the TLS handshake indefinitely. 3. Standalone Conscrypt `SSLContext`, fed through Netty's `SslHandler`. 4. Local stub classes in `javax.security.sasl.*` (`SaslClient`, `SaslException`, `AuthenticationException`, `SaslClientFactory`, `Sasl`) so SCRAM authentication can link. 5. SLF4J binding (see Reliability) — failures in driver background threads are otherwise silent. ### What's not in 0.1.0 (deliberately deferred) Aggregation pipeline builder, schema analysis, index create/drop, validation rules, explain plans, server/database/collection stats, GridFS, Atlas Search indexes, change streams, multiple concurrent connections, document import/export, Atlas Device Sync, iOS or desktop targets, Play Store distribution.
